This maybe a stupid question but i've searched and can't find it. My g/f just bought a 97 civic hx and when it gets warm the idle surges. I'm assuming it's the IACV that just needs to be cleaned.

But I'm not too familiar with the newer cars, I'm used to the 88-91's where the IACV was on the back of the intake. So does anybody have a picture of where the IACV on this car is located?

 

Is the CEL ON?

FYI: Other common causes for surging idle are a vacuum/intake air leak (disconnected hoses?) and air in the cooling system (bleed = fix).

 

Thank you for that. No the CEL isn't on and I just bled the cooling system. There's always a chance that it didn't get all of the air out though.
